ver. 0.292: ShopProduct + ShopPaymentMethod + ShopPromotion + ShopStatuses + ShopTransport frontend migration to Domain

Full migration of front\factory\ — entire directory removed (all 20 classes migrated).
ProductRepository +20 frontend methods, PromotionRepository +5 applyType methods,
TransportRepository +4 cached methods, PaymentMethodRepository +cached frontend methods.
Fix: broken transports_list() in ajax.php replaced with forPaymentMethod().
